Liquid cooler LRC-80 series

laboratoryfor domestic applicationshigh-performance

Product overview
This LRC-80 series closed-circuit recirculating chiller provides controlled cooling from -80°C to -20°C for industrial and laboratory applications. Designed for continuous 24/7 operation, the units use cascade refrigeration and sealed circulation to protect the heat-transfer medium and ensure temperature stability.

Key features

• Closed-cycle pipeline design to prevent contamination of circulating liquid and extend medium lifetime.
• Cascade refrigeration with branded compressors (Tecumseh or Copeland depending on model).
• Temperature range -80°C to -20°C with adjustable 0.1°C resolution and PT100 sensor.
• ASET multifunctional controller with 7-inch color touchscreen and temperature-curve recording/export.
• Multi-level safety: over-temperature, high-pressure, sensor, liquid-level and compressor protection, plus power-on delay.
• Efficient two-stage condensate system and plate heat exchanger for high heat-transfer efficiency.
• High-performance circulation pump for continuous 24-hour operation; pump options available (35/50/110 L/min, higher pressure options).
• MODBUS RTU communication via RS485 for integration with PLC/SCADA.
• Refrigerant: R-404A (all models).
• All components safety-grounded; full closed circulation avoids vapor formation at low temperature.
• Optional materials: SUS304 parts and higher-capacity liquid storage on request.
• Available power configurations: AC220V 50Hz, AC380V 50Hz and optional 220V/60Hz or 440–480V/60Hz three-phase.

• Series: LRC-80 (models LRC-8018N, LRC-8030N, LRC-8062N, LRC-8090N, LRC-80A1N, LRC-80A2N).
• Temperature control: ASET controller; feedback PT100; outlet medium control optional.
• Cooling capacity (@ -40°C): 0.6–7.2 kW depending on model.
• Cooling capacity (@ -60°C): 0.4–6 kW depending on model.
• Cooling capacity (@ -75°C): 0.2–3 kW depending on model.
• Circulation pump flow (standard): up to 20–75 L/min depending on model; optional 35/50/110 L/min and up to 2.5 bar; pressure ≤6 bar option available.
• Liquid storage capacity: 15–45 L standard (larger on request).
• Compressors: Tecumseh or Copeland by model; evaporator: copper-tube.
• Connection sizes: DN15–DN20 (model dependent).
• Typical dimensions & weight (air-cooled, model dependent): ranges provided per model; power consumption varies (examples: AC220V 50Hz 3.5kW up to AC380V 50Hz 13kW).
• Communication: MODBUS RTU (RS485).
• Construction: cold-rolled steel painted standard; SUS304 optional.

Typical applications

• Industrial and R&D temperature control for materials testing and chemical processes.
• Biotech and pharmaceutical labs requiring low-temperature recirculation.
• Cryogenic support for analytical instruments and test chambers.
• Production processes needing reliable closed-loop cooling at extreme low temperatures.

Options & customization

• Circulation pump upgrades (35/50/110 L/min) and higher pressure variants.
• SUS304 construction for wetted parts and larger liquid reservoirs on demand.
• Alternate power supplies and frequency options (220V/60Hz, 440–480V/60Hz three-phase).

Safety & compliance

• Multiple fault alarms: over-temperature, sensor failure, high pressure, compressor overheat, low/high liquid level.
• Self-diagnosis and overload protection for reliable unattended operation.
• Safety grounding for all electrical parts and power-on delay protection.
• Designed to minimize vapor formation and maintain purity of the heat-transfer medium at low temperatures.
